To all whom it may concern:

Be it known that JAMES D. REIFSNYDER and GEORGE H. FATE, citizens of the United States, residing, respectively, at Weehawken and Denver, in the counties of Hudson and Denver and States of New Jersey andColorado, have invented new and useful Imfed individually from a stack to a predeter-' mined point such as a wrapping station, each blank being preferably provided with adhesive after leaving the stack and before reaching such point; in connection with this object the invention preferably provides the adhesive in the form of spots or zones.

Another object of the invention is the provision of means whereby the gumming instrumentality is normally maintained operative to apply the adhesive to the desired portions of the'blank or wrapper present in such instrumentality, with the instrumentality having its elements operating in a predetermined cycle, the means being operative to so affect the operating cycle as to prevent the production of conditions such as would cause a succeeding blank to receive adhesive at an undesired point. 7

A still further object comprises the provision of wrapper blank feeding and gumming mechanism operative to deliver the wrapper to a wrapplng station, means being provided for supporting such wrapper at the'said station under yielding tension for the purpose of folding it smoothly about a package fed in contact therewith.

Further objects are to provide apparatus for this purpose which is simple in construction and operation, durable in construction, and which can be manufactured at a relatively low cost.

. To. these and other ends, the nature of which will be readily understoodas the invention is hereinafter disclosed, said invenand combination of parts, hereinafter fully described, illustrated in the accompanying drawings, and more particularly pointed out in the, appended claims. v

Fig. 7 is a detail sectional view showing the manner of lifting the uppermost blank from the pile or stack. J

Fig. 8 is a similar view showing the manner of transferring the blank from the first to the second feeding mechanism.

Fig. 9 is a detail view showing the application of adhesive to the blank.

Fig. 10 is a similar view showing the manner'in which the blank is released atthe close of the feeding operation.

For the purpose of illustratin the invention we have shown it as applied to a packaging machinein which the blanks bein applied or gummed are adapted to be uti ized 1' Y is given.

The .blanks are carried by a table in the form of a stack, the tablepreferably bein given such movements vertically as will ten to locate the uppermost blank on a proper plane, especially at the time when the picker structure is made operative to select the blank.

The picker structure, in the embodiment shown, is of the suction type, and is shown as mounted on a reciprocating carrier or carriage which serves to advance the selected blank. The icker is made rative at the advance en of the blank-t e ed of the blank which is in advance during t e blank-advancing movement-to raise such end sufficiently to permit the introduction of a plate between the selected blank and the stack, the late being mounted on and movable with t e carrier, being assed to a position to support the selecte blank by the movements of the carrier in one direction; The carrier is also provided with gripthe blank, these latter becoming active on the selected blank as the carrier com letes' the movement which positions the se ected blank on its plate support. Hence, when the direction of movement of the carrier is reversed, the selected blank will be advanced with its advance edge gri pod and with its body portion supported ,on the plate. This mechanism may be considered as a prima feeding mechanism; v

e advance of the blank brings its advance edge into the space between gripping .faces carried by an endless carrier which is adapted to travel only in the direction of advance of the blank. This endless carrier is operated intermittently and (preferably carries several separated orspaee grippin devices, these devices being normally closed: The travel cycle of the endless carrier is movement when one ofthe devices is in position to receive the blank from the advancing carrier of the primary feeding means, the positioned gripping device being open at this time to receive the blank, the device closing to grip the blank and the grippingv faces of't e primary means opening in advance of beginning the retreating movement of the primary means. The travel of the endless carrier then advances the blank to the wrapping station, where the 'pping deviceis temporarily opened to re ease the blank, and de osit it upon supports for resiliently hol ing the blank for the subsequent wrapping operation.

At a suitablepoint, 1n the travel of the blank from the stack to the point. it is released from the endless carrier, adhesive is ap lied to the articular'face of the blank. n the em ent illustrated this adhesive application is made after the blank has been released from the gripping.

faces of the I rimary feeding means, the particular mec anism shown being ada ted to apply spots of adhesive to predetermined portions of the blank, being provided by a rotatable element which carries adhesive and with which a second element is ada ted to 00-0 rate, the latter being arra to norma y form a face in opposition tothe ping means operative on the advance end of be considered as the front of the machine,

so arranged as to provide a dwell in the' where adhesive-applying face, thus providing assurance o a proper adhesive application. In order however, to prevent the second element from receiving the adhesive in case of failure to resent a blank at the proper time, a control mechanism is made active in such manner as to prevent the opposed faces of the two elements passing into direct contact, the result being that adhesive is not transferred to the second element, thefaces of the latter thus being prevented from being placed in a condition to produce undesirable ap lication of adhesive to a susceedin blank.

In tEe drawings, 30 designates a base plate that rests upon the floor and su ports the machine. Bolted to the top 0 the base plate are two-upright skeleton frames 31,

32, one on each, si e of the machine, connected together at their tops at the delivery end of the machine by, a horizontal bed-platev 33. An inverted U-shaped standard 34 is bolted to the bed plate 33 above the side frame 31, while opposite over the side frame 32 is a standard 35. Suitable cross-beams 90, are employed for producing a strong frame for the different mechanisms. For the purpose of clearness, that part of'the machine at the right in Fig. 1 may the direction of blank advance being toward the left in said figure--toward the rear of the machine. 4

Transversely of the machine above the base plate 30 is a horizontal driving shaft 37, mounted in suitable bearings carried by the base plate. On this shaft are secured the various cams and gear wheels by means of which the several parts of the machine are actuated. The shaft 37 rotates continuously during the operation of the machine and may be driven in' the most convenient and suitable way. In the present instance the end of the shaft at the left of the machine carries a, worm gear 39 turned by 'a{1l0 pulley 42 thereto when a. hand lever 44 is rocked. I

I Extending across the front of the machine between the side frames 31 and 32 and connected to said frames is a beam 45 through the center'of which passes a bar 46 slidable 12.0 vertically therein and having on one side a rack 47 engaging a pinion 48 fast on a shaft 49 journaled in the side frames 31, 32, upon rotation of which shaft the rack bar is raised and lowered.v A horizontal table 50 is car-' ried on the top of the rackbar to support a stack of blanks A and moves with said bar. One or more guide pins 51 project downwardly from the bottom of the table 50 and slide through holes in the beam 45 to steady the table and preventitturning. Vertical cured to the frame of the machine if desired.

A fixed finger 56 forms a stop and guide for the blanks at the advance edges of thelatter. Shaft 49 projects through side frame 31 and has aflixed thereon, outside the frame, a worm wheel 57 rotated by a worm 58 mounted on a shaft 59 supported in bearings 60 on said frame. A feather 61 secures the worm on the shaft and permits it to slide longitudinally for a limited distance. On one end of the worm 58 is a grooved collar 62 with which pins 63 on a forked lever 64 engage, said lever being fastened on a short pivot pin 65 that extends through the side frame 31 and there provided with an arm 66 from the end of which a connecting rod 67- extends to a lever 68, pivoted to a fixed bea-ringat one end and engaging at its other end with a cam disk 69 on the drivingsh'aft 37 At each rotation of the driving shaft the cam disk 69 through the connections described, causes the arm 64 to rock and slide the worm longitudinally on its shaft a short distance. This movement of the worm turns the worm wheel 57, its shaft 49 and the pinion 48 on said shaft a sufficient amount to raise the rack bar 46 and the wrapper table carried therebyjor a purpose to be hereinafter described. Upon passi of the cam surface 69 of disk 69, the weight of table 50 and the blanks thereon will return the parts to their normal ositions.

- Over the ta le 50 is the blank feed carrier or carriage 700cm rising two vertically arranged side plates 1 connected attheir tops by a transverse plate 7 2. Legs 73, 74 depend from the bottom edges of the side plates andcarry each two flanged rollers on the outer face, the rollers 75, 76 on each leg being spaced apart in avertical direction. Between therollers 75, 76 on each side of the carriage is a horizontalrail 77 bolted to the respective side frames31, 32 and separated a short distancetherefrom by spacing collars 78. On these rails the carriage travels to and ho to feed the blanks. Fastened on the of the shaft 81 projecting from the bracket '82 on the right side of the machine, with which" engages a toothed segment 84, pivoted at 85 to the side frame 31. From thesegment 84 a rod 86 pivoted thereon extends downwardly and rearwardly toward the driving shaft 37 and is connected at its lower end to a yoke 87, the legs of which straddle the driving shaft and are guided thereby. On one side of the yoke 87 is a. roller 88 that enters a cam groove 89. The cam groove acting through the roller 88 as the shaft revolves, moves the rod 86 longitudinally,

and, rocks the toothed segment 84 which through the pinion 83 oscillates the shaft 81 and gear wheels to advance and retract the carriage 70.

\ Projecting rearwardly from each side plate of the blank carriage 70 is a bracket 90 against the under side of which brackets are secured'the ends of a thin horizontal plate 91 from the advance edge ofwhich pro ects a plurality of tongues 92 while the rear edge extends at anangle from each end to the center forming a slightly projecting lip 93 that is given a downward curve or bend, the shape of which lip is clearly shown in Figs. 5, 6 and 7 Q Journaled in the ends of brackets is a transverse rock shaft 94 on wh ch are fixed a number of fingers 95 that extend toward the rearof the machine in a substantially-horizontal direction, their free ends 96 being bent downwardly and overlying tongues 92. Ends 96: are normallyheld in contact with the tongues by a spring 97 C0118l around one end of the rock shaft and connected thereto and to one of the brackets 90.

An arm 98 projects in a forward direction from the opposite end of the rock. shaft which on being depressed, lifts the fingers .95 from tongues 92.

Fastened on the top of the side frame 31 in rear of the shaft 81 are two bearings 100 on the'innerside of each of which is pivoted a downwardly and rearwardly incllned swinging arm 101, said arms lying parallel with each other and pivotally connected at their free ends by a bar 102. -Upon swinging the arms v101 the bar 102 moves- 1n a vertical plane and when lowered lies-in the I path of arm 98 on rock shaft 94, or a roller on the end of said arm. At the proper time in the feedin of the blank bar: 102 s depressed, there y rocking arm 98 and lifting the free end 96 of the fingers 95 for the purpose of releasi the blank For the purpose of swinging arms 101 and "raisingiand lowering bar 102, a lever 103 is connected to the pivot. of one of said swinging arms 101 and projects rearwardly a short distance. From this lover a connecting-link 104 extends downwardly to a bell-crank lever 105 fulcrumed on the main frame and engaging at its free end with a cam 106 secured on the main driving shaft 37. p

Extending transversely of carriage 70 at its re ar end and 'ournall'ed inthe sideplates 71 thereof is a s aft 107 on the left end of which is a pinion 108 that meshes with a horizontal rack 109 fastened to the to of the side frame 32, Secured to the sha in the longitudinal center of the machine is a hollow roller 110 the chamber 111 therein 7 of its length at least, and opens into chamber 111 in roller 110 from its right end upon which is a con lin 113 of suitable form connected by aexi le pipe 114 with a suction device of any suitable type for causing a current of air to flow continuously inwardly from the hole 112' in the roller 110, thefpirpose of which will be described hereina r.

' The blank feed carriage 70 does not deliver the blanks direct to the particular point of the machine where the wrapping operations take place, but carries them a part of the distance from table 50 to such oint and then transfers them to a second eeding mechanism by means of which the distance is completed, the blanks being carried ast an adhesive-appl ing device during t is travel from the ta 1e. This second feeding mechanism will now be described.

Mounted to turn in the side frames 31, 32 in rear of the blank feeding carriage 70 are two horizontal shafts 115, 116, vertically disposed one above the other "and'at substantially equal distances above and below the plane of the blank feed plate 92. Se-

- /cured on the upper shaft 115 is a gear wheel 117. A' similar gear wheel 118 of equal di- Jameter is secured on-the lower shaft 116.

rection from said sprocket wheels to the bed plate 33. From the These H gear wheels intermesh so that the turning of one will necessitate the rotation Fastened on the upper shaft of the other. a short distance within the side frames 31, 32 are two sprocket gears 119 and 120 around which pass two sprocket chains 121. The chains 121 extend in a horizontal diextreme rear of the machine where they pass over smaller sprocket wheels 122 on a shaft 123'mounted inbearin 124 adjustable in upright brackets 125 bolted to the s rocket wheels 122 the chains extend upwardly and forwardly to sprocket wheels 126 fixed'on a shaft 127 mounted'in bearings on the u per ends of brackets 128 rising from standards 34, 35. From sprockets 126 the chains pass downwardly to sprocket wheel 119, 120. The two sprocket chains carry gripping devices 129 that take the blanks from f and transport them to the pass into the the machine.

Grippers 129, of which there are preferably several attached to the chains 121 and cod carriage connected to one of the chains, the plates in turn being connectedby 'a transverse rod 131 the ends of which enter sockets in the lates .130 and are secured thereto by pins.

we- 0nd rod 132 parallel to rod 131 extends be tween the plates 130 and is pivoted in sockets 133 formed on said plates. Fastened on rod 131 within the width of a blank A are a number of gripping blocks 134 spaced apart, the under surfaces of which are flat as at 135 and from each of which surfaces at the rear depends a small hook-shaped 1i 136. These blocks are secured to the r 131 by set screws, thus permitting their ad- 'ustment on the rod to the width -of the lank. Adjustably fastened on rod 132 are a number of fingers 138 that normally roject toward thefront of the machine w en }in operative position and bear against the at fingers 138 are also adjustable on rod 132 and are equal in number to blocks 134. The fingers are held normally in contact with blocks 134 by means of a spiral spring 139 surface 135' of the block 134. These that surrounds one end of rod 132, said- .s ring having one of its ends attached to t e adjacent plate 130 and the other end to a collar 140 on rod 132. Fastened to the other end of said rod 132 is a short arm 141 which maycarry a roller 142 at its free end that at proper times engages a suitable cam 143 and a stop 152 and be' depressed by said cam and stop swings t e fingers 138 ,away from blocks 134 to receive and disengagek at suitable intervals an edge of the lan 'Mounted to swing on shaft 115. close to sprocket wheel 119 1s said cam 143 that extends downwardl into the path of arm 141 or the roller 142 t ereon.- A lug 144 projects upwardly from the cam above shaft 115 and is. connected by a link 145 to a bell-crank lever 146 pivoted in a bracket 147 bolted on thetop of side frame 31. From lever 146 a connecting rod 148 extends downwardly toward main vdriving shaft 37 and is there pivoted to one arm of a bell-crank lever 149, the other arm of which-or a roller thereon-bears against a cam disk 150 on driving shaft 37. On cam disk 150 is a cam surface 151 that at the proper time rocks bell-crank lever 149 and through the connecting rod 148, bell-crank lever 146 and link 145, rocks cam 143 and swing blocks 134.

Before proceeding further a short de 'scription of the operation of the blank feed carriage 70 in picking up and carrying a blank to the secondary carrier and the manthe fingers 138 away from her of transferring the blank to said carrier to depress arm 141 blank contacts with the under surface of the suction roll 110. At the beginning or during the movement of the feed carriage 70 toward the front of the machine, suction roll 110, moving therewith, is rotated by pinion 108 engaging rack 109. Thepart's are so timed that hole or perforation 112 in the suction roll will be on the under side of the roll when. the latter arrives adjacent the advance end of the wrapper or blank, as shown in Fig. 7. The suction through said roll will hold this edge of the blank againstthe roll and as the carriage starts or continues its travel in this direction, the reverse rotation of the suction rollclockwise in Fig. 7will lift the advance edge of the blank above the stack, as shown in said figure, and permit the downwardly-inclined lip 93 of plate .91--which also reciprocates .with the carriage-to pass below the uppermost blank or between it and the balance of the stack. Finger 54 at the front edge of the stack holds the selected blank against forward movement so that upon completion of this movement of the carriage, the selected blank A will overlie plate 91, the advance edge of the blank being supported by tongues 92 beneath the free ends 96 of fingers 95, the latter being elevated to permit the blank to pass thereunder.

The carriage 70 then reverses its movement to the direction of blank advance, whereupon the swinging arms '101 are actuated by cam 106 to raise bar 102 so that fingers 95 by the force of spring 97 are caused to clamp the blank between their forward ends and tongues 92. The carriage continues this advance movement toward the secondary feeding mechanism which in the meantime has brought one of the gripping devices 129 into position toreceive the blank from the carriage. The-gripping device at this time is stationary and as the carriage, advancing thereto, reaches the limit of 1ts movement, tongues 92 and fingers 95 enter between the blocks 134 of the gripping device. Fingers 138 of this device are, at this moment, in their downward position or away from blocks 134 so that the advance edge of the blank is carried beneath said blocks and above the hook-shaped lips 136 (Fig. 10). Cam 143 now releases arm 141 so that spring 139, turning rockshaft 132, swings fingers 138 up against the under side of the blank and clamps it against the flat surface 135. of blocks 134. At the same time bar 102 is depressed and lifts fingers 95 of the blank feed carria e to release the blank from plate 91. e secondary carrier with its grip ing device 129 now advances while the fee carriage 70 be ins its travel toward the front of the mac ine and begins its cycle of operation on the succeeding blank,

the suction roll picking up the top blank to permit the plate 91 to pass thereunder as heretofore pointed out.

To enable plate 91 to pass freely between the top or selected wrapper blank and the stack of blanks, table 50 is lowered a short distance during each cycle to relieve the roll and not to feed the table and stack gradually upward as the blanks are successively removed fromthe top of the stack. Other means are employed for this gradual feed of the table, which means will now be described.

The toothed segment 84 (Fig. 2), from which motion is imparted to reciprocate the I blank feed carriage, has projecting forward from its hub an arm 153 connected at its end by a'link.154 with a lever 1 55 pivoted to swing freely on the short shaft 59 at the right hand side of the machine. Fixed on said shaft at one side of lever 155 is a ratchet wheel 156 with which a pawl 157 pivoted on lever 1'55 engages. At each operation of the machine to feed the blank the oscillation of the toothed segment84 swings arm 153 which through the connections described actuates the arm 155 in such manner that pawl 157 carried thereby will turn ratchet wheel 156 and shaft59 a short distance. This partial rotation of shaft 59- and worm 58 keyed thereon will 'in turn impart a slight movement to worm wheel 57, a movement suffi cient however to elevate the table 50 a distance to compensate for the blank previously removed. It will thus beapparent that every time a blank is removed from the stack table 50 supporting thestack is elevated a very little but sufiicient to maintain the top of. the stack at a point where the top blank will be located at a substantially constant plane relative to the plane of the suction roll. If from any cause the top of the stack is elevated higher than its normal position, pawl 157 is disengaged from ratchet Wheel 156 by tri 158 lyingc ose to one side of ratchet wheel 156 and having a notch 159 in its periphery which normally is opposite pawl 157 and permits the latter to engage the ratchet wheel, the pawl itself being sufliciently wide mechanism comprising a disk to project beyond said ratchet wheel and over the edge of the disk. Disk 158 turns freely on'shaft 59 and pivotally connected to said disk is a rod 160,- the upper end of which is tion indicated attached to a lever 161 fulcrumed on a bracket projecting from the main frame. A link 162 extends from lever 161 to one end of a second lever 163 pivoted at 164 tothe main frame and provlded on its other end with a shoe 165 that bears upon the topof the stack of blanks. When the stack of blanks is raised to the roper height, as in Fig. 3, the parts just escribed are in the position shown in said Fig, but should the table 50 and blanks be raised above normal even a slight distance, shoe 165 will move with the blanks and this movement, transmitted through levers 163 and 161 and their connections, willturn disk 158 in the direcb the arrow sufliciently far as to swing pawi 157 away from the ratchet wheel 156 and hold it out of engagement therewith until the stack has been lowered to the proper position. During the time disk 158 is .in engagement with pawl 157 the swinging movement of arm 155 will not, as

is evident, cause the actuation of ratchet wheel 156 and through said ratchet wheel thelgradual feeding upwardly of table 50., Tab e 50 is raised and lowered manually whenever desired by placing acrank (not shown) on the projectingend 1660f shaft 1 59, said end havl a polygonal outline as shown to receive t e cran By disenga ing pawl 157 from the ratchet wheel the shaft may be turned in either direction to and cause the raising or lowering of table 50.

The second feeding mechanism is preferably in the form of an endless conveyor inoperation of the machine.

second feeding mechanism by a cam 167 fast on main driving shaft 37 rocking a lever 168 pivoted to side frame 32 near base plate. 30 having a segmental rack 169 on itsupper end that meshes with a gear wheel 170 mounted to turn freely around a stub shaft projecting from side frame 32. Aflixedto gear wheel 170 and turning on the same stubshaft is a larger gear wheel 171 that meshes with a fgear wheel 172 which turns loosely on sha 116. Gear wheel 172 is of less diameter than gear 171 and has fastened to its outer side a disk 173 in whichis formed a ooncentric depression 174.- on its exterior face. Rotating within said'depression is a circular plate 175 "fixed on shaft 116 and having a notch 176 in its edge with which notch en ges a dog 177 pivotally mounted in an 0 set 178 from depression 174; The

ar, wheels are so pro rtioned that at each vibration of lever 168 t e segmental rack 169 car wheel 170 first in one thereon turns direction. and th 11 in the other. This same movement through gear wheel 171 being imparted to the smaller gear wheel 172 turning This intermittent advancing movement is. imparted to said -c0mprises two a freely on shaft 116, the latter gear wheel and movement of se ment 169 rotates disk 173 in the opposite dlrection, but dog'17 7 swinging within its offset 178, is released from plate 175 and returns to its first position while the plate and shaft 116 remain stationa Shaft 116, by means of gearing 118, 11 turns shaft. 115 through .a complete revolution and thus advances the second, feeding mechanism the required distance.

As heretofore pointed out, the apparatus is preferably designed-to apply an adhesive to one face of the blank. For instance, if the blank is being employed forth'e wrapping of a package, the adhesive will permit of securing the folds of the wrapper in position relatively to each other or to the package contents, In the resent embodiment of the invention this esive is applied to the upper face of the blank as it lies extended on the table and passes along in the plane of the feeding movement, the particular point in the travel of the blank from table 50 utilized in this particular embodiment being just after the blank has been gripped by the secondary feeding mechanism, thus locatingthe blank at a convenient point in the specific arrangement of feeding mechanisms shown.

The particular adhesive-applying means shown (Fig. 6)-a form designed for spot or zone application and illustrating the more difiicult phases of adhesive applications 179 adjustably secured on shaft 115, each arm 179 having a jaw 180 on its outer end and within which is clamped a short curved .pad 181. These arms are made adjustable so that they may locate the pads 181 at predetermined points of the blank, these pads being designed toa ply the adhesive ad'acent the lateral edges 0? the blank. Aflixe to shaft 115, between the arms 179, is a plate 182 that extends in a radial direction, the outer edge of said plate having a jaw 183 within which is clamped a straightor lineal paste-applying pad 184, the length of which extends transversely of the machine while the jaws which hold it aresubstantially the same length as the width of the blank. Plate 182 and radial arms 179 stand at such an angleone to the other that as shaft 115 rotates, pads 181 will ap ly the adhesive at each of the side edges 0 the blank at about the center of its 'blan --the end which last passes beneath the adhesive applying device. Arms 185 and a length while pad 184 will apply adhesive l r the entire length of the rear end of the those on,arms 179 and plate 182, are mounted on shaft 116 and extend radially from such shaft at such angles that as the shafts 115, 116, rotate pads 187 on arms 185 will form abutting surfaces for pads 181 as they contact with the blank, and pad 186 serves the same purpose for the pad 184, the blank extending between the opposing faces of the several sets of pads.

form in a trough 189 that extends transversely across the, machine and is supported by extensions 190 from the side frames 31, 32, in rear of shaft 115. Rotatably mounted hesive-collecting roller 191 that dips into the adhesive contained in the trough and picks up the same as it rotates, the excess adhesive being removed from the roller by a scraper 192 in the form of a spring plate,

one end of which bears on roller 191 with greater or lesser pressure as permitted by the regulation of adjusting screws 193. The applying. roller 194 runs; in contact with and transfersi't-to pads 181 and 18,4 asthe latter are carried in the circular path. A

belt pulley 195 loose on the shaft of roller 191 and driven from any suitable source of power turns said shaft when connected thereto by a clutch 196. The applying roller194 is driven positively from-the gathering or collectingroller 191 by intermeshing gear wheels 197, 198 on the shafts of said rollers.

Pads 181 lie at the same distance from the axis of shaft 115, as the chains 121, so that the pads move at the same speed as the blank which is being carried by the chains. The

co-operating pads 187 also move at the same 40 speed so that when the two pads 181 and 187 come together, as indicated in Fig. 9, but separated by the blank A, they move with the blank and at the same speed as the blank.

It may sometimes hap en that a blank fails to enter between t e tongues .92 of plate 91 and fingers 95 above saidplate, and therefore when the carriage 70 moves toward the second feeding mechanism it does so without carrying a blank to the gripping device 129'. If such be the case, when shafts 115 and 116 rotate the pads 181 and 184 carried thereby would contact with pads 187 and 188 and cover the same with-adhesive,-

there being no blank between them. This would, of course, cause great trouble at the next operation when a wrapper blank is fed. To prevent such an occurrence means are provided to prevent the rotation of shafts 115 and 116 when a blank fails to be fed to the second mechanism.

This means comprises a rocking lever 199 (Fig. 4) pivoted on plate 175 that is secured on the outer end of shaft 116. One arm of this lever is in contact with the free The adhesive material is carried in liquid.

in bearings fixed to said extensions is an adroller 191 and taklesadhesive therefrom end of dog 177 and when moved will swing said dog out of notch 176 in said plate, but is normally prevented from doing so by a spring 200. Upon the other arm of the lever 199 rests a finger 201 projecting from a sleeve 202 pivoted on side frame 32. A second finger 203 extends in the opposite direction from sleeve 202 and is provided with a projecting pin 204 on its outer end.

This pin 204 enters an L-shaped slot in a vertical bar 205 pivoted on one end of a rocking lever 206 connected at its other end by a link 207 to an angular plate. 208 mount- 1 ed to swing on a pivot 209 and lying in the path of a cam bar 210 carried by carriage 70. The L-shaped slot within which pin 204 lies has a horizontal leg 211 nornism to carry the blank thereto cam plate 210 strikes swinging plate 208 and through the several connections raises bar 205, but because of leg 212 of the L-shaped slot being in line with pin 204, fingers 201, 203

will remain quiet and at the proper time shafts 1'15, 116 will rotate under the. normal operations, but should there be no blank on carriage 70, bar 205 will be drawn downwardly by means hereinafter described and leg 211' of the .L-shaped'notch will engage pin 204 and as plate 208 is depressed and bar 205 elevated, fingers 201, 203 will be rocked and lever 199 swung to disengage dog 177 from notch 176 in the plate so that rotation of disk 173 will take place without carrying plate 175 with it an'd consequently shafts 115 and 116 will not turn.

The means for swinging bar 205 so that leg 211 of the L-shaped notch can engage pin 204 comprises an electro-magne't 213 mounted onside frame 32 in position to attract bar 205 or an a mature thereon, said. electro-magnet being in circuit with a battery from which wires extend to plate 91 and toan insulated step 214 on the depressed end 96 of one Or more of the fingers 95. When a blank A is between tongues 92 and fingers 95, said blank serves as an insulation and the electro-magnet is not energized, but should carriage 70 advance without a blank the insulated contact, touching tongue 92, would close the circuit through the electro-magnet 213 and attract bar 205', causing leg 211 of the L-shaped slot to engage pin 204 on arm 203.

As will be understood the blank is retained within the grip of the grip ing device 129 during the operation of t e gumming instrumentality, so that the gummed blank will be advanced flatwise in its own plane until stop 152 is reached, thus bringing into operation the releasing action by opening the gripping device. This position is shown in Fig. 10 as located to deposit the gummed blank over the folding well of the wrapping station of the machine.

As, is usual in 'the ackaging or wrapping art, a package is fed into contact with the wrapper positioned over the folding well of the maching, the wrapper being folded about the package as both move intothe folding well. For the purpose of folding the wrapper smoothly about the packa when the latter is fed into contact with the former, I provide means for supporting the blank A at the wrapping stationnnderyielding tension, the wrapper being by this means drawn tightly about the package as both are fed into the folding well of the machine.

- To this end the wrapper, upon the releasing action of. the per device, is, as pointed out above, degd ited over the folding well of. the machine and on a front supporting table 216 and a rear supporting table 217,

see Figure 10) folding well 215 being dened by the space between the said tables 216 and 217; these tables being mounted above the bed plate 33. 'The inner edges of these tables, which overhang the opening 7 or well 215, are each provided with a resilient roller 221. Extending-across each table a short distance back from the rollers 221 is a passage 227, from which passagesmall holes 228 are made to the upper surface of the two tables, said passages 227' being con nected by pipes (not shown). with a suit- 7 formed in a respective tables 216 and 217. As will be able suction device. In the present instance each passage 227 is formed inabar 230, groove extending across the apparent, when a package located above the tables is moved into contact with the wrap-, per A, drawing'the 'sam'e' ofi' the supporting tables and both package and wrapper moving into the folding well 215, the wrappet is drawn tightly about the package as it passes between the-rollers, owing to the fact that the movement of the ends of the wra per is retarded by the suction and sma 1 holes 228 leading thereunto from the top of the tables and which are covered by the wrapper.. The suction tends to draw the in. the blank supporting table 50 is lowered and wra per against the tables and holds them in t s osition; but thedownward movement 0 the pack exertin a greater force than is exerted y the suction, the ends of the wrapper are gradually drawn across the holes 228, the suction through them, however, being sufiicient to hold'the wrapper under such tension as to draw it tightl about the package, effecting a securely fol in function.

, the'operation of the present invention,

a stack of b anks A laced thereon between the side fingers=52, t e finger 54 and finger 56, these latter fingers being located at the front and rear of t e stack, thus alining the be understood as reserving the r stack. The table is then raised into opera;

tive position with the uppermost blank against suction roller 110 and shoe 165 of the tripping mechanism, by manual rotation'of shaft 59. The trough 189 is filled with liquid adhesive and the machine operated sufliciently before feeding blanks as to thoroughly coat rollers 191, 194 and applying pads 181, 184 with the adhesive. The machine .bein now ready for operation,

proper time carriage; with thesuction roller 110 advances over the stack of blanks, roller 110 picking up the advance edge of the uppermost blank at the end of such movement to enable plate 91 to pass between said blank and the stack, during the movement of the carriage in the op osite direction; At the conclusion of such atter movement of, the carriage, the selected blank is clamped between tongues 92 of plate 91 and the pivoted fingers 95, and is .power is applied to main driving shaft 37 by actuating the shifting lever 44. At the advanced by the carriage at the next -feeding the travel the blgnk passes the adhesive applying mechanism and receives the adhesive on its upper face. Should the primary feeding mechanism fail to properly position the blank on the plate 91, the trip mechanism described is made active through the completion of the circuit between finger 96 and tongues 92-these acting'on the order of a detecting mechanism -thus setting in motion the structure which prevents the adhesive applying mechanism' from bringin'guthe opposing sets of pads into physical contact, the 'feeding mechanisms simply continuing their regular cycles of opera-v tion, so that sto ping of the machine is unnecessary to talie care of the failure of blank feed.

As heretofore indicated, the particular construction shown is more or less illustrative.
